Abstract:Hollow spherical aminofullerene aggregates encapsulating L-cysteine (L-Cys@NFH) were prepared by ethylenediamine (EDA) modification followed by liquid-liquid interfacial precipitation (LLIP) method. The composition, microstructure, and particle size distribution of L-Cys@NFH were characterized using FTIR, XPS, EA, SEM, TEM and EDS. The biocompatibility
